Re: So its just anothe phone now, not special?
Note4 is 699 unlocked on Verizon, with better hardware.
At $350 its easy to excuse the N5 shortcomings. At $650 the N6 cannot have any.
I don't know about better hardware. Motorola have better signal and call quality than even Samsung, and build quality as well, even with that aluminum frame for this Note4 this time.
MicroSD inclusion and removable battery do not constitute better hardware. I see removable battery as a con, and not everyone care for microSD, most regular users don't even use it. It's the techie that care about microSD and removable battery. Finger print scanner and heat rate sensors are useless gimmicks, I do not even want them on a phone.
As for the camera the jury is still out. It's using the Sony Exmor 214 which is used by the best Android phones right now with OIS. Motorola post processing software sucks, but Android L have a new camera API. I don't know how good it is going to be, but it will be at least better than the Moto X.
Also the combination of Android L and stock Android undoubtedly will allow it to have longer battery life than the Note 4 with Touchwiz. There are couple things Note 4 have like the SPen and Touchwiz features, but you have to realize, not everyone want those Samsung things which is why they look to a stock Android device like this.
PS. $699 on Verizon is still on Verizon, which have very pricy plans. Most people who use Nexus prefer unlocked GSM phones and ability to switch carriers freely. These two phones appeal to different type of users.
